The message selection issue

[Dy1anT]

I have a question: why is a list of messages used in the code, and then the following code is used in the WmProcessorMessageModel to select one of these messages? What is the significance of doing so?

cur_message = self.message[message_len // self.encode_len]

if the message is long, we split it into several parts and encode each independently. For example, if we have 100 bits to encode, we may turn it into a list of five 20-bit parts and encode each into 200 tokens. This is because directly encoding and decoding a single message with too-many bits is too computation-expensive.
